Which outcome occurs when oxygen outcompetes carbon dioxide within a plant's bundle sheath cells?

💡 Explanation

Photorespiration occurs due to oxygen outcompeting carbon dioxide, causing the enzyme rubisco to bind with O2 rather than CO2, resulting in the breakdown of RuBP and decreased photosynthetic output. Therefore photorespiration occurs, rather than CO2 fixation, because rubisco's affinity changes.
